FIELD AND BACKGROUND OF THE INVENTION

The present invention, in some embodiments thereof, relates to Brucella phage nucleic acid sequences and uses thereof.

Brucella are Gram negative, small coccobacilli bacteria. They are animal pathogens causing abortions in the natural hosts, in the latest period of pregnancy. Genus Brucella includes 10 species divided to smooth and rough outer membrane LPS bearing organisms. Three smooth Brucella species, (B. melitensis, B. abortus and B. suis) associated with small ruminant, bovid and swine brucellosis, respectively, are zoonotic to humans. Less frequently, B. ceti and B. pinnipedialis associated with marine mammal brucellosis have been documented as causative agents of human brucellosis. In addition, B. canis that is associated with canine brucellosis is a rough organism that causes human infection. The disease in humans is presented as undulant fever also known as Malta fever, and it may sequel to a chronic disease or manifestation of meningitis, osteomyelitis, endocarditis and other complications. In rare occasions the disease may become fatal.

Brucella phages are bacterial viruses specific to Brucella species. A review of Brucella phages and their taxonomical relatedness was published in 1981. All contemporarily known Brucella phages were shown to comprise a similar icosahedral head and short tail morphology belonging to the family Podoviradae. The studied phages were shown to be closely related according to antigenic and physiological properties and resistance to chemical and physical agents. These findings have led the authors to include the summarized variants within a single species and propose phage Tb as type virus (Ackerman, H.-W., Simon, F., and Verger, J.-M. 1981. Intervirology 16: 1-7).

Brucella phages have linear double stranded DNA in size around 38 kilo base pairs. Restriction enzyme digestion analyses of phages Tb, Fi, Wb, Iz and R/C have shown similarity amongst the DNAs and little evidence has been found for lysogenic existence of the phages or presence of plasmid forms in the hosts.

Previous studies have established guanosine—cytosine content of 45.3-46.7% in phage Tb whereas a higher percentage of 48.9% was anticipated in other phages.

Use of phages as therapeutic agents of a pathogenic disease has been indicated by several researchers (Brussow, H. 2005. Microbiol. 151: 2133-2140; Summers, W. C. 2001. Ann. Rev. Microbiol. 55: 437-451).

In addition, Brucella phages have been employed in Brucella typing and a phage susceptibility test has become instrumental in classification and establishing a taxonomical tree of genus Brucella. Specifically, it was suggested that division of genus Brucella into nomen-species is partly justified according to their species specific phage susceptibilities that also correlated well with host affiliation of the strains. Brucella phages have been divided into 7 groups according to their infectivity to Brucella spp. Phage Izatnagar (Iz₁) represents group 6 that is infective to all smooth Brucella nomenspecies and partly to rough strains (Corbel and Tolari, 1988, Res Vet Sci; 44: 45-49).

DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

The present invention, in some embodiments thereof, relates to Brucella phage nucleic acid sequences and uses thereof.

Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details set forth in the following description or exemplified by the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways.

The Brucella species are important zoonotic pathogens affecting a wide variety of mammals. In agriculturally important domestic animals, these bacteria cause abortion and infertility, and they are of serious economic concern worldwide. Brucella species that infect humans cause an undulating fever, which if untreated, can manifest as orchitis, osteoarthritis, spondylitis, endocarditis, and neurological disorders. In rare events it may be fatal.

The present inventors have sequenced the entire genome (38,254 base pairs) of the Brucella phage Iz₁ as a genotype representative of all other Brucella phages. Two genomic Brucella phage Iz₁ populations were identified, differing between C or A at nucleotide 5549. BLAST analysis of this sequence revealed 6 regions of homology with Ochrobactrum anthropi ATCC 49188 chromosome 1—see Table 2 in the Examples section herein below. Subtraction of these sequences from the sequence of the full length genome, leads the inventors to the discovery of novel polynucleotide sequences which are specific to Brucella phage (e.g. SEQ ID NOs: 387-393).

The information gleaned from the sequence has allowed the inventors to identify apparent sequence of minimal presence of ORFs, which can be used for inserting genes of interest (for example, those encoding detectable moieties) into the phage, without affecting its lytic activity. Thus, development of a recombinant Brucella phage has been sought based on recombinational replacement of this site in the phage genome with a detectable signal (e.g. Lux operon). Due to the outputting of this signal, such a phage could be used to identify Brucella bacteria. Phage carrier Brucella clones were generated in which phage Iz₁ coresided in the cells in presence of plasmid pBBR1mcs4.1-II1053/Lux_(CDABE)/15B-18B (FIG. 3B), providing unlimited opportunities for recombinantional events to occur between the Lux operon on the plasmid DNA and the Brucella phage DNA.

In addition, the present inventors have identified regulatory regions in the phage which possess regulatory function and were shown to be capable of down-regulating light expression endowed by the plasmid indicating potential implementation of such a gene regulation mechanism within Brucella bacteria.

Thus, for example, the present inventors identified a fragment of phage DNA which can down-regulate a gene operatively linked thereto (SEQ ID NO: 396; 19630-18579) following transformation into Brucella bacteria. When this sequence was transformed into Brucella bacteria, together with an additional phage DNA fragment (SEQ ID NO: 397; 16509-15500), it conferred different lethal activities on Brucella species, being the most lethal to lethal to the B. abortus strain 544, less severely lethal to B. melitensis and non-lethal to the B. suis strain of Brucella. Correspondingly, the down-regulatory activity of this fragment was also shown to be species specific.

Knowledge of phage regulatory regions should add to computational identification of additional unrecognized regulatory sequences within the genome of Brucella. This approach has already been demonstrated in the legume endosymbiont Sinorhizobium meliloti (del Val C, et al., Mol Microbiol 2007; 66: 1080-1091), that is belonging to the alpha-proteobacteria class, as also Agrobactrum tumefaciens, the causative agent of crown-gall disease in plants and Brucella, indicating close relatedness and therefore possible shared functions between these organisms (Inon de lannino N, et al., J Bacteriol 1998; 180: 4392-4400).

Thus, according to one aspect of the present invention, there is provided an isolated polynucleotide comprising a nucleic acid sequence of a Brucella phage, the nucleic acid sequence being specific to the Brucella phage and comprising a sequence selected from the group consisting of SEQ ID NOs: 387-393.

As used herein, the term “phage” (synonymous with the term “bacteriophage” refers to a virus that selectively infects prokaryotes—such as bacteria. Many bacteriophages are specific to a particular genus or species or strain of cell.

The phage is typically a lytic bacteriophage.

A lytic bacteriophage is one that follows the lytic pathway through completion of the lytic cycle, rather than entering the lysogenic pathway. A lytic bacteriophage undergoes viral replication leading to lysis of the cell membrane, destruction of the cell, and release of progeny bacteriophage particles capable of infecting other cells.

A lysogenic bacteriophage is one capable of entering the lysogenic pathway, in which the bacteriophage becomes a dormant, passive part of the cell's genome through prior to completion of its lytic cycle.

According to one embodiment, the phage is a Tb type phage, for example Phage Iz₁.

A sequence specific to a Brucella phage is one which is present in the phage and not present in other organisms—i.e. unique to Brucella. Since the sequence of the Brucella phage genome is now known, Brucella phage specific sequences may be identified using BLAST or other similar programs.

According to one embodiment, the Brucella phage specific sequence does not comprise more than 70% identity with another nucleic acid sequence as verified using a sequence alignment software such as BLAST analysis.

According to one embodiment, the Brucella phage specific sequence does not comprise more than 60% identity with another nucleic acid sequence as verified using a sequence alignment software such as BLAST analysis.

As used herein the phrase “an isolated polynucleotide” refers to a single or double stranded nucleic acid sequences which is isolated and provided in the form of an RNA sequence, a complementary polynucleotide sequence (cDNA), a genomic polynucleotide sequence and/or a composite polynucleotide sequences (e.g., a combination of the above).

As used herein the phrase “complementary polynucleotide sequence” refers to a sequence, which results from reverse transcription of messenger RNA using a reverse transcriptase or any other RNA dependent DNA polymerase. Such a sequence can be subsequently amplified in vivo or in vitro using a DNA dependent DNA polymerase.

As used herein the phrase “genomic polynucleotide sequence” refers to a sequence derived (isolated) from a chromosome and thus it represents a contiguous portion of a chromosome.

As used herein the phrase “composite polynucleotide sequence” refers to a sequence, which is at least partially complementary and at least partially genomic. A composite sequence can include some exonal sequences required to encode the polypeptide of the present invention, as well as some intronic sequences interposing therebetween. The intronic sequences can be of any source, including of other genes, and typically will include conserved splicing signal sequences. Such intronic sequences may further include cis acting expression regulatory elements.

According to one embodiment, the isolated polynucleotide comprises at least 15, at least 20, at least 40, at least 50, at least 100, at least 200, at least 500 or at least 1000 consecutive nucleotides of the sequences as set forth in SEQ ID NOs: 387-393.

Thus, the polynucleotides of the present invention may be from 15-38,254 nucleotides long.

It will be appreciated that homologues of the sequences described hereinabove are also envisaged by the present invention. Accordingly, the polynucleotides of this aspect of the present invention may have a nucleic acid sequence at least 50%, at least 55%, at least 60%, at least 65%, at least 70%, at least 75%, at least 80%, at least 85%, at least 87%, at least 89%, at least 90% at least 91%, at least 93%, at least 95% or more say 100% identical to the sequences derived from SEQ ID NOs: 387-393, as determined using BlastN software of the National Center of Biotechnology Information (NCBI) using default parameters.

Thus, the present invention encompasses nucleic acid sequences described hereinabove; fragments thereof, sequences hybridizable therewith, sequences in the opposite orientation thereto, sequences homologous thereto, sequences encoding similar polypeptides with different codon usage, altered sequences characterized by mutations, such as deletion, insertion or substitution of one or more nucleotides, either naturally occurring or man induced, either randomly or in a targeted fashion.

Exemplary polynucleotides contemplated by the present invention are those that comprise the nucleic acid sequence as set forth in SEQ ID NOs: 1 and 387-393.

Other exemplary polynucleotides contemplated by the present invention are those that comprise regulatory regions within the sequences as set forth in SEQ ID NOs: 387-393, such as at least 100 consecutive nucleotides of the regulatory region as set forth in SEQ ID NO: 395 shown by the present inventors to possess down-regulating activity of a gene operationally linked thereto, when inserted in the opposite orientation (i.e. SEQ ID NO: 396). Another regulatory sequence includes SEQ ID NO: 394, both in the forward or reverse orientation. This is also present in the complete phage genome possibly affecting regulatory functions of phage Iz₁ genes.

Using bioinformatic tools, the present inventors identified additional regulatory regions within the full length sequence of the phage genome which may serve as promoter sequences (i.e. transcriptional regulatory regions) in the phage (SEQ ID NOs: 2-386). Such promoter sequences may be placed upstream of a heterologous nucleic acid sequence so as to promote transcription thereof. Moreover, the downregulatory activity might be used to identify important chemicals that change the activity of the transcriptional regulatory regions, thereby facilitating development of novel drugs.

Other sequences which encode putative polypeptides are also provided and also considered to be in the realm of the present invention. Such sequences are provided in Table 1 herein below. Polynucleotide sequences encoding such polypeptides may be used for various purposes. Thus, for instance a polynucleotide sequence encoding a putative lysin or holin may be used to selectively kill Brucella cells. The advantages of lysin-based therapy are numerous: they can be prepared with high purity and possess high specific activity; they exhibit rapid lethal action; they are nontoxic; and apparently, antibodies that form against these proteins do not neutralize their lytic activity. Lastly, no bacterial resistance develops to these proteins, probably because they possess multiple domains for cell wall binding and hydrolysis.

Examples of additional important polypeptides are:

1. Secretory proteins including flagellar proteins (secretion Type III, This apparatus is related to the injectisome used by many gram-negative pathogens and symbionts to transfer effector proteins into host cells) and VirB (Type IV, The translocation of DNA across biological membranes is an essential process for many living organisms. In bacteria, type IV secretion systems (T4SS) are used to deliver DNA as well as protein substrates from donor to target cells. The T4SS are structurally complex machines assembled from a dozen or more membrane proteins in response to environmental signals The translocation of DNA across biological membranes is an essential process for many living organisms. In bacteria, type IV secretion systems (T4SS) are used to deliver DNA as well as protein substrates from donor to target cells. The T4SS are structurally complex machines assembled from a dozen or more membrane proteins in response to environmental signals)

2. Phage integrase—catalyses the site specific integration and excision of the bacteriophage in the lysogenic cycle.

3. Toxins, phospholipase—degrade phospholipids, protease—degrade proteins.

As mentioned herein above, the present invention also contemplates isolated polynucleotides which hybridize to the isolated polynucleotides described herein above. Such polynucleotides may be used to monitor Brucella phage gene expression, eventually allowing detection of Brucella strains (i.e. diagnosing) in a bacterial contaminated environment.

Such polynucleotides typically comprises a region of complementary nucleotide sequence that hybridizes under experimental conditions to at least about 8, 10, 13, 15, 18, 20, 22, 25, 30, 40, 50, 55, 60, 65, 70, 80, 90, 100, 120 (or any other number in-between) or more consecutive nucleotides to the sequence of the Brucella phage.

The polynucleotide (or plurality thereof) may be fixed to a solid support (e.g. in an array) and may be used to monitor phage expression in a Brucella sample.

Alternatively, the polynucleotide may serve as a primer in a primer pair and may be used in an amplification reaction (e.g. PCR) to identify Brucella phage.

The conditions are selected such that hybridization of the polynucleotide to the Brucella phage sequence is favored and hybridization to other non Brucella phage nucleic acid sequences is minimized.

By way of example, hybridization of short nucleic acids (below 200 bp in length, e.g. 13-50 bp in length) can be effected by the following hybridization protocols depending on the desired stringency; (i) hybridization solution of 6×SSC and 1% SDS or 3 M TMACI, 0.01 M sodium phosphate (pH 6.8), 1 mM EDTA (pH 7.6), 0.5% SDS, 100 μg/ml denatured salmon sperm DNA and 0.1% nonfat dried milk, hybridization temperature of 1-1.5° C. below the Tm, final wash solution of 3 M TMACI, 0.01 M sodium phosphate (pH 6.8), 1 mM EDTA (pH 7.6), 0.5% SDS at 1-1.5° C. below the Tm (stringent hybridization conditions) (ii) hybridization solution of 6×SSC and 0.1% SDS or 3 M TMACI, 0.01 M sodium phosphate (pH 6.8), 1 mM EDTA (pH 7.6), 0.5% SDS, 100 μg/ml denatured salmon sperm DNA and 0.1% nonfat dried milk, hybridization temperature of 2-2.5° C. below the Tm, final wash solution of 3 M TMACI, 0.01 M sodium phosphate (pH 6.8), 1 mM EDTA (pH 7.6), 0.5% SDS at 1-1.5° C. below the Tm, final wash solution of 6×SSC, and final wash at 22° C. (stringent to moderate hybridization conditions); and (iii) hybridization solution of 6×SSC and 1% SDS or 3 M TMACI, 0.01 M sodium phosphate (pH 6.8), 1 mM EDTA (pH 7.6), 0.5% SDS, 100 μg/ml denatured salmon sperm DNA and 0.1% nonfat dried milk, hybridization temperature at 2.5-3° C. below the Tm and final wash solution of 6×SSC at 22° C. (moderate hybridization solution).

The polynucleotides may further be labeled with detectable moieties. Methods for labeling nucleic acid molecules are well-known in the art. For a review of labeling protocols, label detection techniques, and recent developments in the field, see, for example, L. J. Kricka, Ann. Clin. Biochem. 2002, 39: 114-129; R. P. van Gijlswijk et al., Expert Rev. Mol. Diagn. 2001, 1: 81-91; and S. Joos et al., J. Biotechnol. 1994, 35: 135-153.

As mentioned, the present inventors have identified a region within the Brucella phage genome which serves as a regulatory sequence in Brucella and other bacteria—see Table 3 of the Examples section herein below.

Thus, according to another aspect of the present invention there is provided a method of down-regulating expression of a gene of interest in bacteria, the method comprising transforming bacteria with a nucleic acid construct which comprises a Brucella phage regulatory sequence, thereby down-regulating expression of the gene of interest.

The phrase “Brucella bacteria” as used herein, refers to all strains of Brucella including, but not limited to B. abortus strain 544, B. Suis strain 1330 and B. melitensis strain 16M. According to a particular embodiment, the downregulating is effected in the B. Suis strain or the B. melitensis of Brucella.

Examples of bacterial constructs include the pET series of E. coli expression vectors [Studier et al. (1990) Methods in Enzymol. 185:60-89). An example of a bacterial construct which allows expression in Brucella bacteria is the plasmid pBBR1mcs-4 (Kovach et al., 1995, Gene 1995; 166: 175-176), the contents of which are incorporated herein by reference and the pNSGroE plasmid (Seleem et al., BioTechniques 37:740-744 (November 2004), the contents of which are incorporated by renference herein.

It will be appreciated that the method of this aspect of the present invention may be used to down-regulate expression of a gene which is endogenous to the bacteria or endogenous to a phage which is comprised in the bacteria.

The gene of interest is preferably downregulated by at least 10%. According to one embodiment, the gene of interest is downregulated by about 50%. According to another embodiment, the gene of interest is downregulated by about 90%.

Examples of genes of interest include genes that encode polypeptides important for survival of the bacteria. By down-regulating such genes, the method may be used to kill the brucella bacteria, thereby treating a brucella infection.

The present invention contemplates insertion of transposon sequences on either side of the regulatory region such that it can be randomly inserted via a transposition event into the bacterial genome or site specific designed mutation.

As used herein, the term “transposition event” refers to the movement of a transposon from a donor site to a target site.

As used herein, the term “transposon” refers to a genetic element, including but not limited to segments of DNA or RNA that can move from one chromosomal site to another.

An exemplary transposon sequence is provided in SEQ ID NO: 398 (ME1 transposon sequence) and SEQ ID NO: 399 (ME2 transposon sequence). For directed down-regulation of a particular gene, bacterial sequences may be added on either side of the regulatory region, to facilitate a recombination event.

According to one embodiment, the regulatory region comprises from 100 to all the nucleotides of the nucleic acid sequence as set forth in SEQ ID NO: 396 (19630-18579).

Optionally, the nucleic acid construct comprises additional regulatory regions such as the one set forth in SEQ ID NO: 397 (16509-15500).

According to a particular embodiment, the nucleic acid construct further comprises a heterologous nucleic acid sequence and upstream thereto, a promoter sequence which directs expression of the heterologous nucleic acid sequence. The promoter sequence is selected such that it allows transcription of the heterologous nucleic acid sequence in the bacteria. Thus an exemplary promoter that may be used in Brucella is one set forth in SEQ ID NO: 400. Another promoter that may be used to express a heterologous nucleic acid sequence in Brucella include the groE promoter [Saleem et al., BioTechniques 37:740-744 (November 2004)]. Additional prokayotic promoters are also contemplated by the present inventors which are known in the art.

The regulatory region (for example SEQ ID NO: 396) is typically placed immediately downstream to the heterologous sequence in order to down-regulate expression thereof.

An exemplary construct contemplated by the present invention that may be used to show that SEQ ID NO: 396 comprises regulatory activity may comprise as follows:

i. a polynucleotide encoding a gene of interest (e.g. detectable moiety) operationally fused to a Brucella promoter; and

ii. a Brucella phage sequence fused to a 3′ end of the gene of interest, the regulatory sequence comprising from 100 nucleotides to all the nucleotides of the nucleic acid sequence as set forth in SEQ ID NO: 396.

Optionally, the construct may also comprise:

iii. a Brucella phage sequence fused to a 5′ end of the promoter, the sequence comprising from 100 nucleotides to all the nucleotides of the nucleic acid sequence as set forth in SEQ ID NO: 397.

It will be appreciated that when the heterologous nucleic acid sequence encodes a detectable moiety, it may be used to determine a strain of Brucella. The present inventors have shown that a plasmid construct comprising SEQ ID NO:396 placed immediately downstream of a detectable moiety can downregulate its expression in a strain specific manner. Thus, expression of the detectable moiety was almost completely down-regulated in B. suis and only partially down-regulated in B. melitensis. Such a construct can also be used to determine which bacteria are sensitive to the brucella phage regulatory region and engineer these bacteria by gene down-regulation. In addition, the construct may be used as a tool to decipher novel factors that modify promoter activity by analysis of the detectable signal.

The detectable moiety is typically comprised in a reporter polypeptide which emits a detectable signal. It may be a fluorescent signal (e.g. green fluorescent protein (GFP) red fluorescent protein (RFP) or yellow fluorescent protein (YFP)); a luminescent signal (e.g. luciferase—LUX) or a color signal (e.g. β-glucuronidase (GUS) and β.-galactosidase). In addition, transcribed RNAs of the polypeptides can be used as reporter products of the system.

According to a specific embodiment of this aspect of the present invention, the heterologous nucleic acid sequence encodes a LUX operon. Such an operon is encoded by the sequence as set forth in SEQ ID NO: 401. Further information regarding LUX operons may be found in Winson M K, Swift S, Hill P J, Sims C M, Griesmayr G, Bycroft B W, Williams P, Stewart GSAB. 1998, Engineering the luxCDABE genes from Photorhabdus luminescens to provide a bioluminescent reporter for constitutive and promoter probe plasmids and mini-Tn5 constructs. FEMS Microbiol Letteres 163: 193-202; Craney A Hohenauer T, Xu Y, Navani N K, Li Y, Nodwell J. 2007. A synthetic luxCDABE gene cluster optimized for expression in high-GC bacteria. Nuc Acid Res 35: No. 6 e46, both of which are incorporated herein by reference.

The present inventors identified sequences in the Brucella phage genome which were devoid of open reading frames and generated constructs which facilitated insertion of genes of interest (for example, those encoding detectable moieties) into the Brucella phage at those positions, so as not to affect the vital life cycle of the phage.

Thus, according to yet another aspect of the present invention there is provided a nucleic acid construct comprising:

i. a polynucleotide encoding a gene of interest operationally fused to a Brucella promoter;

ii. a first Brucella phage sequence fused to a 5′ end of the promoter, the first sequence comprising from 100 nucleotides to all the nucleotides of the nucleic acid sequence as set forth in SEQ ID NO: 394; and

iii. a second Brucella phage sequence fused to a 3′ end of the gene of interest, the second sequence comprising from 100 nucleotides to all the nucleotides of the nucleic acid sequence as set forth in SEQ ID NO: 395.

Since the flanking sequences around the gene of interest (i.e. SEQ ID NO: 394 and SEQ ID NO: 395) are Brucella phage sequences, such a construct may be used to insert the gene of interest by recombination into the Brucella phage genome.

If a phage is required which may be used to identify Brucella bacteria (and diagnose an infection), the gene of interest may encode a detectable moiety. Detectable moieties are further described herein above.

If a phage is required which may be used to kill Brucella bacteria, the gene of interest may encode a polypeptide which is lethal to Brucella bacteria. Such polypeptides may include anti-bacterial toxins (bacteriocins) and the like. In addition, non-translated sequences may be used to down-regulate important bacterial functions and factors that affect these sequences could be exploited to control bacterial functions.

Examples 3 and 4 of the Example section herein below describe a method of generating Brucella bacteria which carry the phage as co-residence of recombinant strains. Such carrier Brucella clones provide a means of unlimited chances to achieve direct recombinantional events between harbored foreign DNA and Brucella phage.

It will be appreciated that the phage which identifies Brucella bacteria by outputting a detectable signal (or carrier Brucella clones comprising same) may be used to diagnose a Brucella infection in a subject.

According to this aspect of the present invention, the method of diagnosing comprises contacting a sample of the subject with the recombinant Brucella phage described herein above.

General Materials and Methods

Purification of Phage Iz₁ and extracting genome DNA: Phage Iz₁ was consecutively propagated on Brucella abortus reference strain 544 by inoculating drops of a phage Iz₁ suspension at routine test dilution (RTD) concentration on tryptic soy agar plates on which a 0.1 ml aliquot of a B. abortus strain 544 suspension was spread. After overnight growth at 37° C. in 5% CO₂ atmosphere plaques were collected into tryptic soy broth and enumerated for further preparations of RTD suspensions used in phage typing of Brucella isolates.

The same procedure was applied in order to purify phage Iz₁ particles for DNA extractions. However, phage suspension was prepared in TMGS buffer and filtered twice, first through 0.45 μm and subsequently through 0.2 μm filters in order to achieve a non-Brucella contaminated phage suspension.

2 ml of phage suspensions were centrifuged per tube using Sorvall RC M100 ultracentrifugation (Du-Pont). Ultracentrifugation was carried out at 10° C., for 4 hours at 60,000 rpm and DNA was extracted from phage pellets using QIAamp DNA Mini Kit, according to manufacturer's instructions (Qiagen GmbH, Hilden, Germany).

Cloning Phage Iz₁ HindIII DNA fragments—construction of phage Iz1 HindIII fragment clones in E. coli plasmid pBlueScript: Phage Iz₁ DNA was digested by HindIII, according to manufacturer's instructions (Fermentas Inc., Maryland, USA). The HindIII digestion profile concurred with previously published data (Rigby et al., Can J Vet Res. 1989; 53: 319-325). The DNA fragments were purified from agarose gel using Wizard® SV Gel system (Promega). Plasmid pBlueScript was digested by HindIII and purified from agarose gel using Wizard® SV Gel system (Promega). The purified pBlueScript plasmid and Phage Iz₁ DNA fragments were mixed, ligated and transformed to E. coli JM109 (Promega). Plasmid DNAs were extracted using HiYield Plasmid Mini Kit (RBC Bioscience, Taipei County, Taiwan).

DNA-DNA hybridizations: Hybridization was executed using DIG nonradioactive nucleic acid labeling and detection system, according to manufacturer's instructions (Roche Diagnostics GmbH, Mannheim, Germany).

Construction of plasmid pBBR1mcs-4.1-II1053Lux_(CDABE): Plasmid pBBR1mcs-4 1-II1053Lux_(CDABE) was constructed by inserting the Photorhabdus luminescens luxCDABE operon (Winson et al., 1998, FEMS Microbiol Letters 1998; 163: 193-202, incorporated herein by reference) into plasmid pBBR1mcs-4 (Kovach et al., 1995, Gene 1995; 166: 175-176).

Construction of plasmids pBBR1mcs-4.1-II1053Lux_(CDABE) (15B-18B and 15A-18A, respectively) Specific Phage Iz₁ sequences were used as scaffold of the plasmid constructs. Primers were designed to include both Tn5 mosaic ends, 1 and 2, respectively. The KpnI::PstI sequence was added 5′ and PvuII::ME-1::KpnI sequence added to the 3′ end of fragment 15500 to 16509 of Phage Iz₁ amplicon. The SacI::ME-2::PvuII sequence was added 5′ and SalI::SacI added 3′ to 18579 to 19630 fragment of Phage Iz₁ amplicon (PvuII, KpnI, SacI, SalI are nucleotide sequences of the restriction endonuclease restriction sites of these enzymes; The position of the primers used to generate these constructs is illustrated in FIG. 4.

Phage Iz₁ naked DNA was used as the substrate in separate PCR DNA amplification reactions to obtain the desired amplicons. The first fragment [SacI::ME-2::PvuII-Iz(18579-19630)-SalI::SacI] was digested with Sad then ligated into a Sad linerized plasmid pBBR1mcs-4.1-II1053Lux_(CDABE) to generate an intermediate plasmid pBBR1mcs-4,1-II1053Lux_(CDABE)::Sack:ME-2::PvuII-Iz(18579-19630)-SalI::SacI, in orientations A and B (FIG. 3B). These plasmids were then used to construct the two complete plasmid structures shown in FIG. 3B by KpnI linearization of these constructs and ligation with fragment [KpnI::PstI-Iz(15500-16509)-Pvuth:ME-1::KpnI] that established the two complete constructs shown in FIG. 3B. Importantly, Plasmid 15A-18A establishes an intact Tn5 transposon construct that includes Phage Iz₁ genome sequences flanking pLux. In contrast, plasmid 15B-18B includes pLux as an intact Tn5 transposon and phage Iz₁ sequences correctly orientated in the flanking ends of the intact Tn5::pLux construct.

Establishing phage Iz₁ pre-infected-electro-competent Brucella suis strain 1330 cells: Brucella suis strain 1330 was grown at 37° C. in 5% CO₂ atmosphere for 2 days on Trypticase soy agar supplemented with Serum-dextrose (Alton G G, Jones L M, Angus R D, Verger J M. Techniques for the brucellosis laboratory. Institute National de la Recherche Agronomique, Paris. 1988). Cells were collected by a plating loop and transferred to 6 ml Tryptic soy broth (TSB) establishing cell suspension at a concentration of around 10⁷-10⁸ cells/ml. Then, 1 ml of the cell suspension was inoculated into 22 ml of TSB in a 250 ml Erlenmeyer vessel and laid down to chill in the refrigerator for 2 hours. In total, 4 such Brucella suis strain 1330 cell suspensions were prepared. Incubation was stopped by taking each vessel out from the incubator to ambient temperature and 1 ml phage Iz₁ in TSB at x10⁴ concentration of the routine test dilution (RTD, Alton et al., 1988) were added to the Brucella cell suspension. Taken that Brucella complete a single cycle of cells replication by 4 hours Brucella phage infection was allowed to a minimal period of 2 hours by incubating the cell suspension at 37° C. in 5% CO₂ atmosphere and chilling the cell suspension immediately after by incubation in ice. Then, the 4 cell suspensions were centrifuged for 13 minutes at 6500 rpm, in a fixed angle rotor at 4° C., each in a separate tube. The supernatants were spilled and every two cell pellets were pooled together and resuspended in 12 ml of 10% glycerol solution in double distilled water pre-cooled to 4° C. Washing in the cold (including pre-cooled pipettes and micro-tips) was repeated 4 times, each carried out by resuspending the pellet and repeated centrifugation for 13 minutes at 8000 rpm. The two cell pellets were resuspended and pooled together in 3 ml 10% glycerol and spun down at 8000 rpm for 10 minutes, at 4° C. The final cell pellet was then resuspended in 0.5 ml of pre-cooled 10% glycerol solution and further divided to aliquots of 50 μl each in pre-cooled eppendorf tubes that were immediately cooled to freezing using liquid nitrogen and then stored at −80° C. until use.

Example 1 Deciphering the Complete Phage Iz₁ Genome Sequence

Results

The complete genome sequence of phage Iz₁ has been deciphered using 454 Life Sciences™ Roche GS-FLX sequencing platform (DYN Labs, LTD, Israel). The largest contig that was identified includes 38,254 bp (SEQ ID NO: 1 and SEQ ID NO: 2). Within this contig, the present data identified two Brucella phage Iz₁ genome populations differing by an SNP or a heterozygote nucleotide (nucleotide 5546 was recorded as N but in fact it was conclusively identified as C, and the polymorphism was distributed equally in 8 contigs between C or A at nucleotide 5549, respectively (FIG. 1).

To further corroborate the sequence of the phage, 8 HindIII DNA digest segments (1.1, 2.1; 3.1; 4.1, 5.1; 5.2; 5.3; 7.3) from phage Iz₁ were sub-cloned into plasmid pBS and sequenced corroborating the established sequences of identical overlapping fragments in phage Iz₁ genome. In concordance with these results, whole genomic naked DNA of phage Iz₁ hybridized with each of these clones. Two additional clones, e.g., 5.4 and 71_(—)3 and 71_(—)5_I, included partial sequencing (FIG. 2).

The sequence of the phage was analyzed using BLAST ((Basic Local Alignment Search Tool) software.

The results are displayed in Table 2, herein below.

Results from the analysis of CpG islands show that although the observed/expected ratio>0.60, the actual percent C+percent G>50.00, indicating that the phage comprises sequences other than Brucella.

An inverted repeat was found at positions 5088-5179 and 5405-5310 suggesting a putative site of the origin of replication.

Using an internet based promoter finding tool (worldwidewebdotfruitflydotorg/seq_tools/promoter) the present inventors identified 183 potential promoters on the forward strand and 201 potential promoters on the reverse strand. The sequences of these promoters are set forth in SEQ ID NOs: 3-185 for the forward strand and 186-386 for the reverse strand.

Example 2 Regulating Brucella Genes by Phage Iz₁ Sequences

Plasmid constructs that include selected sequences from Phage Iz₁ genome were designed and transformed to E. coli JM109 including those indicated in FIG. 3B and Table 3, herein below. The plasmid constructs were then transformed to E. coli S17, as this strain supports plasmid transfer to Brucella by conjugation, and selecting Brucella clones by growth on ampicilin. Trans-conjugant Brucella strains with these constructs endowed specific clones with Lux activities that depended on the Phage Iz₁ inserts and the specific Brucella strain that was transformed with these plasmids. B. suis reference strain 1330, B. melitensis type strain 16M and B. abortus reference strain 544 have shown similar strong constitutive Lux expression, based on the promoter upstream of the Lux operon, when harboring plasmid pBBR1mcs4.1 II1053Lux_(CDABE)/15B-18B (see FIG. 3B). In contrast, plasmid pBBR1mcs4.1 II1053Lux_(CDABE)/15A-18A was lethal to B. abortus strain 544 (it was impossible to establish trans-conjugant clones with this construct even if ampicilin was reduced to 25 μg/ml, that is one forth of the normal selective concentration used with B. suis strain 1330). The same applied less severely to B. melitensis strain 16M that was selected on agar plates with ampicilin at concentration of 50 μg/ml. Only B. suis strain 1330 was successfully transformed with the plasmid construct using ampicilin at a concentration of 100 μg/ml. This proves that the Phage Iz₁ sequences conferred different lethal activities on Brucella species as the same plasmid that does not contain phage sequences could be successfully transformed to each of these Brucella strains.

Further, light activity was completely silenced in B. suis strain 1330 whereas it was partially expressed in B. melitensis strain 16M (Results could not be shown with B. abortus as the plasmid was lethal to this strain, as explained above). When arguing for silencing activities by Phage Iz₁ sequences this could be demonstrated by adding external n-decanal to Brucella suspensions. The pentacistronic Lux operon consists of a luxAB component that encodes for a bacterial luciferase that oxidizes FMNH₂ and a long-chain aliphatic aldehyde (n-decanal substrate) in the presence of molecular oxygen to yield a 490-nm optical signature. The aldehyde is subsequently regenerated by a multi-enzyme reductase complex encoded by the luxC, luxD, and luxE genes. Accordingly, the Lux operon is encoding two separate functions, expression of luciferase by genes A and B and the substrate, by genes, C, D and E, respectively. External N-decanal could be used as a substitute for the native substrate. Because the addition of external n-decanal to the cell suspension fully restored light in both B. suis strain 1330 pBBRImcs4.1 II1053Lux_(CDABE)/15A-18A and B. melitensis strain 16M pBBRImcs4.1 II1053Luxc_(DABE)/15A-18A, this indicates that luciferase was present in the reaction mixture at the time, inferring it was fully expressed under the promoter that resides upstream to Phage Iz1 15A and LuxC and Lux D, sequences. It is most likely therefore that gene LuxE, downstream of LuxA and LuxB was under unique regulation from Phage Iz₁ 18A sequence under the 3′ orientation. This is further supported by the fact that this regulation was exerted at different intensities between B. suis strain 1330 (null Lux activity) and B. melitensis strain 16M (partial Lux activity). As phage Iz₁ fully lyses B. abortus and B. suis strains but has only partial lysis on B. melitensis strains, our data corroborate the historical Brucella species phage typing method and support our invention that the 18A Phage Iz₁ sequence regulates Brucella gene expression.

Table 3, herein below provides additional plasmids comprising phage Iz1 sequences that are capable of down-regulating genes placed immediately downstream thereto in both brucella and other bacteria.

pII1053 is strongly expressed in a constitutive manner in the three Brucella species, B. suis, B. melitensis and B. abortus. This promoter is expressed less intensively in E. coli.

The construct 18A downregulates Lux expression in both E. coli and Brucella, most likely by silencing LuxE.

Example 3 Establishing Phage Iz₁ Pre-Infected-Electro-Competent Brucella suis Strain 1330 Cells

In this example, the goal was to develop a method that will extend existence of phage Iz₁ infection of Brucella to an un-limited period of time in order to enable phage genome engineering at that time by recombinant DNA technology.

Naked phage DNA exists within bacterial cytosol immediately after phage infection following intrusion of the bacterial envelop by the phage DNA. Phage replication further ensues due to controlling bacterial gene expression and gearing the bacterial DNA replication machinery to a phage system. Prevention of DNA packaging into intact phage particles will therefore allow gene engineering of the phage genome by electroporation of the bacterial host during this period with recombinant DNA constructs that facilitate gene transposition or gene recombination. Accordingly, the present inventors hypothesized that phage infection could be arrested by chilling the Brucella host cells immediately after infection, then washing the Brucella cells several times using water-glycerol and freezing the cells at −80° C. until needed for electroporation.

Results

One eppendorf tube that contained phage arrested infection as described above, was taken out from the −80° C. freezer, and the cells were thawed on ice, and diluted to 1 ml by adding 0.95 ml of SOC-B solution (Lai F, Microb Pathog 1990; 9:363-368). Then, 1:10 dilutions of the cell suspension were prepared in cold physiological saline solution, up to 10⁻⁷. Drops of 10 μl were then inoculated on B. abortus strain 544 that was spread (0.1 ml of a TSB heavy cell suspension) on a TSA plate by a bacterial Drigalski spreader.

For comparison, an aliquot of the SOC-B cell suspension was passed through 0.45 μm syringe filter in order to ascertain that free Iz₁ phage particles did not exist in the cell suspension. The filtrate was similarly diluted 1:10 in physiological saline solution and 10 μl drops from each dilution were inoculated on B. abortus strain 544 plate (see above).

The two plates were incubated over night at 37° C. in 5% CO₂ atmosphere. The next day, plaques were sought in each dilution of whole cell suspension and cell-filtrate. The last dilution of the cell filtrate that yielded phage plaques was 10⁻² in which only two plaques were identified. In agreement with the dilution around 200 plaques were identified at 10⁻¹ dilution, indicating a minimal presence of free phage particles in the whole cell suspension prior to filtration. In contrast, the last dilution that yielded phage plaques by the whole cell suspension was 10⁻⁶, at which a single plaque was identified. In agreement with the dilutions, 10 plaques were identified at dilution 10⁻⁵ and concentrated plaques were found at 10⁻⁴ and below, indicating existence of close to a 4 logarithmic higher magnitude of phage particles in the cell suspension compared to the cell filtrate. All together, these data support the working hypothesis that despite interfering with phage replication by cooling off the cell suspension, cold washings and freezing at −80° C., the phage infection was fully restored when the cells were thawed and re-cultured. Similar results were achieved when phage infection was stopped after 1 hour and 15 minutes.

Example 4 Development of a Brucella Reporter Clone

The present example describes how a pre-phage infection state could be used to develop a recombinant phage Iz₁ clone that induces Lux activity in Brucella species. Such a recombinant clone could be used as a highly sensitive reporter to indicate presence of living Brucella cells in a suspected sample by light measurements in a host, its tissues (such as aborted placenta and fetus membranes and fluids) or milk samples.

Method

The method involves two steps (See FIG. 5). Firstly, a hybrid DNA was established between phage Iz₁ genomic DNA and plasmid pBBR1mcs4.1-II1053Lux_(CDABE)/15B-18B. Then, this hybrid DNA was electroporated to electrocompetent phage Iz₁ pre-infected B. suis strain 1330 cells and the cells were selected for ampicilin resistance. Phage Iz₁ carrier clones were identified amongst the growing colonies.

1. Establishing Hybrid DNA

A short denaturation and annealing process between equal amounts of phage Iz₁ and plasmid pBBR1mcs4.1-II1053Lux_(CDABE)/15B-18B DNAs was applied, the latter shares homologous sequences with the phage genome (FIGS. 3A-B). The final annealing step was stopped by bringing the reaction to 4° C., in order to establish hybrid DNA molecules between hybridizing single stranded DNAs of the two entities.

DNA denaturation and annealing was carried out in total volume of 25 μl reaction mixture using Biometra, T-Gradient, thermocycler, Germany. The thermocycling reactions were as follows:

Pre-heating: 95° C.-1.30°

6 cycles of: 95° C.-1.15′, 55.5° C.-2.00′, 72° C.-2.00°

Final annealing at 55.5° C.-7.00°

Stop at 4° C.

2. Electroporation

Electrocompetent pre-phage Iz₁ infected B. suis cells were used. 40 μl of electrocompetent cells were electroporated by adding 2 μl of the final thermocycling reaction mixture using bacterial mode of MicroPulser™, BIO-RAD, Hercules, Calif., USA (2.49 Kv, 4.9 ms). Immediately after electroporation, cells were suspended in 1 ml SOC-B (see above) and incubated with shaking at 37° C. for 1 hour and 30 min. A 1:10 dilution of the SOC-B electroporated cell suspension was prepared and 10 μl aliquots from both undiluted and 1:10 diluted SOC-B suspensions were inoculated on TSA plates that included 50 μg/ml ampicillin as the selecting antibiotic.

As a control, 10 μl drops of the electroporated cells in SOC-B and 1:10 dilution were inoculated on B. abortus strain 544 cells that were pre-spread on TSA agar plate in order to demonstrate phage Iz₁ infection of the electroporated B. suis strain 1330 cells.

Results

Non-electroporated cell suspension successfully grew on plain TSA plates but did not grow on TSA plates that included 50 μg/ml ampicillin. After electroporation, about 90 colonies grew on selective agar from the non-diluted SOC-B cell suspension and about 9 colonies grew from the 1:10 cell dilution. Four colonies from each dilution were selected for further analysis, each transferred on a TSA plate that included 50 μg/ml ampicillin. Table 4 herein below summarizes the luminescence and phage activity of electroporated clones.

These results indicate the following: 1. Plasmid pBBR1mcs4.1-II1053Lux_(CDABE) was successfully transformed into these clones. 2. Smooth clones (2, 3, and 4) did not secret phage activity and rough clones were phage carriers (FIG. 5).

Although the invention has been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims.
